In use, by flowing the cooling liquid in the surge bin 25 into the water delivery pipeline 221, the cooling liquid in the water delivery pipeline 221 flows into the serpentine pipeline 32 through the converging pipe 223, when the cooling liquid flows once through the serpentine pipeline 32, the heat of the injection molding cavity is taken away, and then the cooling liquid flows out from the other end of the serpentine pipeline 32 and enters the surge bin 25 through the liquid inlet 23.
In this embodiment, the outer circulation pipe 4 includes a liquid inlet pipe 41 and a liquid outlet pipe 42, one end of the serpentine pipe 32 is connected with the liquid inlet pipe 41, the other end of the serpentine pipe 32 is connected with the liquid outlet pipe 42, the other end of the liquid inlet pipe 41 is connected with the liquid outlet port 24, the other end of the liquid outlet pipe 42 is connected with the liquid inlet port 23, so that the circulation and transportation of cooling liquid can be conveniently performed, the cooling liquid can flow between the built-in cooling component 3 and the external cooling component 2, the cooling effect is improved, and a circulation pump is installed on the outer circulation pipe 4, so that the circulating flow rate can be controlled.
Specifically, two support tubes 323 are mounted on top of the serpentine circuit 32, both support tubes 323 being in communication with the lumen of the serpentine circuit 32. The two support tubes 323 can ensure the support fixation of the serpentine circuit 32.
Further, a water level sensor 251 and a temperature sensor 252 are installed inside the surge bin 25, so that the temperature and the water level of the water can be conveniently detected.
Further, the top of the water pipe 221 is provided with a water inlet end 222, the water inlet end 222 is communicated with the inner top of the surge bin 25, and an electromagnetic valve is installed on the water inlet end 222. By controlling the number of opening of the solenoid valves, it is convenient to control the number of opening of the heat radiating cylinders 22.
Further, the height of the liquid inlet 23 is higher than that of the water inlet 222, so that the liquid is guaranteed to enter the heat dissipation barrel 22 from the water inlet 222 after entering the buffer bin 25.
